# Two lists of sentences
sentences1 = ['如何更换花呗绑定银行卡',
              'The cat sits outside',
              'A man is playing guitar',
              'The new movie is awesome']

sentences2 = ['花呗更改绑定银行卡',
              'The dog plays in the garden',
              'A woman watches TV',
              'The new movie is so great']

# Compute embedding for both lists
embeddings1 = model.encode(sentences1)
embeddings2 = model.encode(sentences2)


# Compute cosine-similarits
cosine_scores = cos_sim(embeddings1, embeddings2)
